Abstract

Eine Elektro-Handwerkzeugmaschine mit einem Gehäuse (12), das einen Elektromotor (14, 140, 141) aufnimmt, der einen Rotor (16) mit Wickelkopf (17) und einem drehsicher befestigten Ventilator aufweist, der eng benachbart zum Wickelkopf (17) sitzt, wird dadurch kostengünstiger herstellbar, leichter und robuster, dass sich der Ventilator (32) zumindest bereichsweise axial bis unmittelbar an die Stirnseite des Wickelkopfs (17) erstreckt - zumindest im radial äußeren Bereich des Wickelkopfes.
